Tamerlan Tsarnaev, a suspect in Monday's Boston Marathon bomb who was killed by police last night, appears to have been an amatuer boxer in the Boston area. According to a thread on Boxrec.com's message board, Tsarnaev competed at 201 pounds in 2009, dropping a bout to Chicago's Lamar Fenner in the 2009 National Golden Gloves. Monday's attack at the finish line of marathon running's premier event killed three people and was believed to have been pulled off by Tsarnaev and his brother Dzokhar. A massive manhunt for Dzokhar has shut down the entire city of Boston. --Scott Shaffer
